ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A318-111 and -112 airplanes; Model A319-111, -112, and -
115 airplanes; Model A320-214

[[Page 4170]]

airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes. 
This AD was prompted by reports of cracked cadmium-plated lock nuts 
that attach the hinge to the fan cowl door. This AD requires inspecting 
to determine the serial number of each engine fan cowl door, inspecting 
for cracking of the hinge lock nuts of any affected door, and replacing 
the lock nuts if necessary. We are issuing this AD to detect and 
correct cracking of the hinge lock nuts, which could result in 
separation of the hinge from the fan cowl door, in-flight loss of the 
door, and consequent damage to the airplane.

DATES: This AD becomes effective March 1, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 1, 
2016.

SUPPLEMENTARY INFORMATION

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Airbus Model A318-111 
and -112 airplanes; Model A319-111, -112, and -115 airplanes; Model 
A320-214 airplanes; and Model A321-111, -112, -211, -212, and -213 
airplanes. The NPRM published in the Federal Register on July 2, 2015 
(80 FR 38036).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0276, dated December 19, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A318-111 and -112 airplanes; Model A319-111, -112, and -115 airplanes; 
Model A320-214 airplanes; and Model A321-111, 112, -211, -212, and -213 
airplanes. The MCAI states:

    In-service findings have been reported of cracked cadmium plated 
lock nuts. This cracking occurs shortly after installation. 
Investigation results attribute the cause to an improper 
manufacturing procedure of the nuts. It was determined that the 
affected batch of lock nuts was used on the fan cowl to attach 
hinges to the cowl doors on CFM56-5B engines only.
    This condition, if not corrected, could lead to separation of 
the hinge from the fan cowl door, possibly resulting in in-flight 
loss of a fan cowl door, with consequent damage to the aeroplane 
and/or injury to persons on the ground.
    For the reasons describes above, this [EASA] AD required 
identification of the affected fan cowl doors, a one-time inspection 
of the fan cowl door hinge nuts and, depending on findings, 
replacement of the affected nuts.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-1991-0003.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 38036, July 2, 
2015) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 38036, July 2, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 38036, July 2, 2015).

Related Service Information under 1 CFR part 51

    Airbus has issued Service Bulletin A320-71-1062, dated July 28, 
2014. Goodrich Aerostructures has issued Service Bulletin RA32071-151, 
dated June 11, 2014. The service information describes procedures for 
inspection and replacement of the hinge nuts of the fan cowl door. This 
service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 437 airplanes of U.S. registry.
    We also estimate that it takes about 2 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $0 per product. 
Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $74,290, or $170 per product.
    We have received no definitive data that would enable us to provide 
a cost estimate for the on-condition actions specified in this AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between

[[Page 4171]]

the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
